91. Example using MPI_BCAST


Up: Broadcast Next: Gather Previous: Broadcast

The examples in this section use intracommunicators.
Example

Broadcast 100 ints from process 0 to every process in the group. 


    MPI_Comm comm; 
    int array[100]; 
    int root=0; 
    ... 
    MPI_Bcast( array, 100, MPI_INT, root, comm);
As in many of our example code fragments, we assume that some of the variables (such as comm in the above) have been assigned appropriate values.
